Worked on the twentyhq/twenty repository to address stability and accessibility issues in long-form content editing. Focused on improving the Rich Text Editor by fixing scroll behavior so that lengthy content remains accessible within the editor and side panel, ensuring UI elements like collapse buttons stay visible. Utilized React, styled-components, and TypeScript to implement viewport-aware scrolling, popup containment, and layout adjustments, such as setting minimum heights and scrollable regions. All changes were thoroughly tested with end-to-end scenarios and passed code quality checks. Collaborated across teams to validate improvements, resulting in a more robust and accessible front end editing experience.
